Claims. (Cl. 235-6048) This invention relates to accounting and similarcalculating machines, and is more particularly concerned with mechanismfor controlling the selection and engagement of the totalizers fordifferent types of operations.

This application is a division of the co-pending application for UnitedStates Letters Patent filed on December 6, 1947, by Raymond A. Christianof al., Serial No. 790,032, now United States Patent No. 2,626,749.

Modern business systems are so diverse, and, in some instances, socomplex, that it is necessary that machines should be extremely flexiblein character. For this purpose it is particularly desirable that, in amachine including a plurality of totalizers, such as adding andsubtracting totalizers, their selection and engagement should becontrolled so as to give the greatest flexibility of control by thesimplest possible means.

Therefore it is the principal object of the present invention to providea simple, economical, and efiicient mechanism for enabling anyadd-subtract totalizer to be controlled from the control keys of thekeyboard for adding, subtracting, and total-taking operations.

Another object of the invention resides in the provision of novel meansfor controlling the various functions of the machine either from thetraveling paper carriage or from certain of the manipulative keyssituated on the keyboard of the machine.

Still another object of the invention is to provide a novel mechanismfor reversing the sign of theentries into the various totalizers on anygiven operation of the machine, thereby enabling erroneous entries to beeasily and quickly removed from the machine, and also for enablingreverse operations to be performed whenever this becomes necessary ordesirable in performing the work at hand.

With these and other objects in view which will become apparent from thefollowing description, the invention includes certain novel features ofdesign and combinations of parts, a preferred form or embodiment ofwhich is hereinafter described with reference to the drawings whichaccompany and form a part of this specification.

In the drawings:

Fig. 1 is a perspective view of the complete machine.

Fig. 2 is a plan view of the calculating machine and typewriterkeyboards of the machine shown and described herein.

Figs. 3A and 3B, taken together, constitute a longitudinal sectionalview taken just to the right of one of the amount banks.

Fig. 4 is a left side elevation of the right-hand bank of functioncontrol keys.

Fig. 5 is a perspective view of one of the control keys shown in thepreceding figure.

Fig. 6 is a detail view of an interlock between certain of the controlkeys shown in Fig. 4.

Fig. 7 is a diagrammatic view showing the various slides associated withthe right-hand bank of control keys.

Fig. 8 is a sectional view of the right-hand bank of function controlkeys taken on the line 7-7 in Fig. 4.

Fig. 9 is a left side elevation of the centre bank of function controlkeys showing in particular the cooperation between these keys and thetotalizer control slides lying therebeneath.

Fig. 10 is a diagrammatic view showing the various slides associatedwith the centre bank of control keys.

Fig. 11 is a cross-sectional view taken on the line 11-11 in Fig. 9.

Fig. 17 is a fragmentary view showing a portion of the manual keyrelease mechanism.

Fig. 18 is a detail view of the rack control pawl mechanism which isrendered effective on total-taking operations to prevent jumping of thedifferential actuators.

Fig. 19 is a view showing in further detail the mechanism illustrated inthe preceding figure.

Fig. 20 is a left side elevation of the various control mechanisms whichare mounted on the outside of the left side frame of the machine.

Fig. 21 is a detail view showing part of the key locking mechanismprovided in this machine.

Fig. 22 is a detail view showing part of the key latching mechanism forthe amount banks.

Fig. 24 is a sectional view taken through the totalizers of the machine.

Fig. 25 constitutes a left side elevation of the front portion of thepresent machine.

Fig. 26 is a fragmentary view showing a portion of the mechanismillustrated in Figure 28.

Fig. 27 is a left side elevation of the mechanism controlled by thetravelling paper carriage for selecting the totalizers for addition,subtraction, or total-taking operations.

Fig. 28 is a view similar to that shown in the preceding figure, butincluding in addition thereto the mechanism for reversing the add orsubtract selection of the totalizer.

Fig. 29 is a plan View showing the totalizer control slides and thesymbol-printing control slides, together with the studs on the controlkeys which cooperate with these slides.

Fig. 30 is a disassembled perspective view of one of the carriage stopsused for controlling the various functions of the machine in accordancewith the columnar position of the traveling paper carriage.

Fig. 31 is a fragmentary view showing the forward end of the No. ltotalizer slide and certain of the symbolprinting control mechanismcooperating therewith.

Fig. 32 is a detail view of one of the carriage stops which is used tocontrol the various functions of the machine.

Fig. 33 is a left side elevation of a portion of the subtotal-takingcontrol mechanism.

Fig. 34 is a front elevation of a portion of the mechanism for releasingthe function control keys automatically during the machine cycle.

Fig. 35 is a left side elevation of the automatic release mechanism forthe function control keys.

Fig. 36 illustrates a part of the totalizer-engaging mechanism as viewedfrom the left-hand side of the machine.

Fig. 37 is a left side elevation showing in further detail thetotalizer-engaging mechanism and the means whereby
